3*Claims. .1

This invention relates towapad'to be .placedlbetween upper and. lower dentures-and the. gums of .the user. A, primary purpose. ofl-theiinvention isto provide a'limited area throughout which fibers, suchas cotton fibers arranged primarily in parallel alignmentcan be permitted to move within..a restrictedzone. "The restriction is provided in my invention "by .fstitching fthrough cotto'n batting at regular intervals so that. the intervening zones are provided between thestitchingLan'd at the same time furrows orggrooves are provided across the batting.

The regularly spacedstitching transverselyof the .'.general .fialignment L of the individual fibers keeps the cotton"fib'ersfrom separatin which would permit the plate land gums to come into contact one with the other, thus destroying the very purpose of the pad.

I am aware of the fact thatcotton fibers in a batt form have' beenipreviously usedpbut I have made the discovery that by providing the spaced apart stitching transversely of thefibers -the cotton contrary". tosho'rt"life'heretoiore secured will la'stithroughout" at I'e'a'SVan'entireiLday. Moreover the user of mWm'vention 'caneat'berries' readily without the seeds bothering or tearing apart the cotton, since the seeds will become imbedded in the cotton safely without causing irritation, and Without cutting the fiber to that extent where it will spread apart and leave the gums exposed directly to the surface of the denture.

A further important object of the invention is to provide a tighter and more secure fit of the dentures in ones mouth. In fact by the use of my discovery, the wearer of dentures employing my invention can eat ear corn very readily without any rocking of the dentures.

Other objects and advantages of the invention reside in its extreme simplicity and low cost to the user.

In describing the invention, reference is made to the accompanying drawing, in which Fig. 1 is a view in top plan of a pad involving the invention designed for an upper plate;

Therearedgeflro'f the pad lil'jis out ongals 'ightline'thereacross. The pad is is 'madeiout .oftcotton' battiligiWhereinthe fibers are originally/combed tolielimrnore*orless parallel "alignment, "and those *fibers are felted substantially together-sothatin the pad l fl these fibersextend in the fore an'd' aft arrange'ment.

ricross thefibers or thepad HI there are: providedta p lurality -of*r'ows I 5- 'of s'titbh-in'g wherein the-stitching loo-ps arespaced-around abofit onesixteenth of -an inch i in length. The wows of stitching I 5 areispaced apartoneiifromi-theiother on tthe iorder 40f from one-half eto five-eighths ofian inch.

The stitching in .therows l'5aisgpulledrrather tightlyso as to press the fibers: alongs't-hose rows into :snug engagement to wreduce -the original thickness of the batting from approximately onequarter to five-sixteenths of an inch to approximately one-sixteenth in the rows.

The pad. It) thus described being fitted down closely within the plate ll has the rows I5 extending transversely across the plate ll so that there will 'be no spreading apart of the individual fibers one from the other transversely of the plate. The fibers do not tend to spread apart longitudinally so much as they do laterally, particularly with the stitching, because those fibers are interengaged between the loops of the stitching, and the interengagement of the fibers between the rows is suflicient to prevent the spreading apart in the longitudinal direction.

In reference to the pad I8, Fig. 4, which is designed for use in a lower plate Hi, the pad I8 is made in the form of a rectangular strip of the cotton batting with the fibers thereof running longitudinally of the strip. Then there is placed across the strip It a plurality of spaced apart rows of stitching 20, the spacing apart being substantially that as is employed in the pad l0. Likewise the fibers are arranged or selected in the batting to run longitudinally of the strip so that the stitching rows 20 extend transversely thereacross.

The pad or strip I8 thus formed is folded downwardly into the plate IS in a more or less U- shaped manner as indicated in Fig. 5, the width of the pad l8 being such that the marginal edges will be within the marginal edges 2| and 22 of the plate l9. As indicated in Fig. 6, the pad l8 thus forms an insulating medium between the surface of the gum 23 and the inner face of the plate l9. Here again, the cross stitching prevents the spreading apart of the fibers laterally one from the other so that fibers are maintained in that insulating condition throughout a long range of usage, in spite of becoming wet with saliva.

It is this question of wetting by saliva and liq-' uids taken into the mouth which causes the deterioration of the pads very quickly with the omission of the stitching. I have discovered that this stitching, quite simple in itself, performs a wonderful function in making the device operate to the satisfaction of the user who has theretofore occasioned no end of difiiculty with his false teeth. 7

While I have herein shown and described my invention in the best form as now known to me, itis obvious that structural variations may be employed without departing from the spirit of thecinvention, and I therefore do not desire to be limited to that precise form beyond the limitations which may be imposed by the following claims.

I claim:

1. A denture pad comprising a cotton batt having the fibers therein generally arranged to be substantially parallel longitudinally of the pad; and stitching extending in lines at intervals transversely across the pad; the spacing apart of said lines exceeding the lengths of said fibers; said stitching having its loops elastically compressing the cotton therein; whereby the pad, within the controlled limits of further possible compression of the cotton within said loops due to pull on the stitching along said lines thereof, may be stretched transversely, and also the pad may be stretched to a greater degree 1ongitudinally between said lines.

2. A denture pad comprising a cotton batt having the fibers therein generally arranged to be substantially parallel longitudinally of the pad; and stitching extending in lines at intervals transversely across the pad; the spacing apart of said lines exceeding the lengths of said fibers; said stitching having its loops elastically compressing the cotton therein; whereby the pad, within the controlled limits of further possible compression of the cotton within said loops due to pull on the stitching along saidlines thereof, may be stretched transversely, and also the pad may be stretched to a greater degree longitudinally between said lines; the lengths of said loops being approximately one-fourth of the original thickness of the pad.

3. A denture pad comprising a cotton batt having the fibers therein generally arranged to be substantially parallel longitudinally of the pad; and stitching extending in lines at intervals transversely across the pad; the spacing apart of said lines exceeding the lengthsof said fibers; said stitching having its loops elastically compressing the cotton therein; whereby the pad, within the controlled limits of further possible compression of the cotton within said loops due to pull on the stitching along said lines there- 'tudinally between said lines; the length of said loops being approximately one-fourth of the original thickness of the pad; the thickness of D the pad being approximately one-fourth of an inch, and said spacing of the stitching lines being approximately twice the thickness of the pad.
